BACKGROUND OF THE INVENTION

The Field of the Invention

The present invention relates to analyte measurement systems. Morespecifically, the present invention relates to analyte measurementsystems having a removable strip port module.

Background

One of the tools used in diabetes management is an analyte measurementdevice (or analyte meter). An analyte measurement device is typicallyused to measure the blood glucose level of a person based on a sample ofblood. In practice, a user inserts an analyte test strip into a teststrip port of the measurement device. The user then lances her finger toobtain a small sample of blood. The blood sample is then placed onto theanalyte test strip, and the measurement device analyzes the bloodsample. The measurement device then typically displays a blood glucoselevel from the analysis.

In order to ensure an accurate measurement is being generated, it isnecessary to keep the measurement device free from contamination. Thereare instances where the strip port may become contaminated with blood orother fluids (e.g., calibration fluid). When this occurs, theperformance of the measurement device suffers and the user is no longerassured an accurate result. As such, the user may need to purchase a newmeasurement device.

Dedicated hospital meters, for example, have high occurrence rates ofcontamination due to factors such as heavy use, need for calibration,disinfection protocols, and other environmental factors. Contaminationof a hospital meter, and the subsequent need to replace the hospitalmeter, is costly. Further, the inventors have found that a substantialnumber of hospital meters are returned to the manufacturer simplybecause the strip port has been contaminated, while most of the otherparts of the meter remain entirely functional.

Additionally, hospital meters that are used in isolation facilities aresubject to strict disinfection protocols to ensure that the meter isfree from bacteria or harmful microorganisms. Such protocols includeharsh cleaning agents, as well as specialized carrying cases orisolation bags to prevent the meter from contacting a patient.

Another disadvantage of typical hospital meters is that they are manytimes too large and cumbersome for neonatal screening. Typical hospitalmeters are difficult to maneuver within the restricted confines of aneonate bed. While portable hand-held blood analyte meters have beenavailable for many years, most portable hand-held meters are intendedfor self-monitoring of individuals, and lack the functionality ofprofessional dedicated hospital meters. Dedicated hospital meters, forexample, include functionality such as (but not limited to): multiplepatient use; tracking of patient and/or operated identification; barcodescanning of patient, operator, or test strips; database management; datatransfer; system-wide connectivity; etc.

DETAILED DESCRIPTION OF THE INVENTION

Before the embodiments of the present disclosure are described, it is tobe understood that this invention is not limited to particularembodiments described, as such may, of course, vary. It is also to beunderstood that the terminology used herein is for the purpose ofdescribing particular embodiments only, and is not intended to belimiting, since the scope of the embodiments of the invention will belimited only by the appended claims.

Embodiments presented herein relate to systems and methods where arelatively smaller sub-assembly (e.g., removable strip port module)serves as an extension of a dedicated hospital analyte meter. Thesub-assembly is designed to facilitate “bedside” testing of a patient.For example, in one embodiment, a removable strip port module isconnected to an analyte meter through a physical connection, such as anextension cable. In another embodiment, the removable strip port moduleis connected to the analyte meter through a wireless interface. Duringtesting, the removable strip port module can be separated from the meterand used to test the patient. As such, the meter does not need to becarried to the patient.

In one embodiment, a removable strip port module is a mechanical andelectrical sub-assembly that “plugs” into the Analog Front End (AFE) ofan analyte meter via a connector. The connector may be a cable, cord, orother extension piece that routes data and/or other electrical signalsfrom the removable strip port module to the meter. The removable stripport module and/or meter may include mechanical engagement features tohouse the module and/or assist in the connection between the module andthe meter.

In one embodiment, the removable strip port module includes a test stripreceptacle mounted on a printed circuit board assembly (PCBA)daughter-card. The test strip receptacle and PCBA daughter-card are thenenclosed in a module housing with a slit or aperture at one end, for thestrip port opening, and an opening for a cable exiting on the other end.The cable is attached to the PCBA daughter-card, for example, throughsoldering or heat-bar. The opposite end of the cable may have aconnector to interface with a mating connector within the meter. Thecable may be a fixed length or retractable/extendable. The PCBAdaughter-card may also have active components, such as op-amps, andsupporting passive components in order to enhance the signal strengthand assure adequate electrical signal levels reach the meter AFE.Alternative embodiments may include a rigid flex cable design; apress-fit engagement between the module and the meter; a through-hole inthe meter for cable access; surface mounted connectors; a ribbon cable;mechanical potting; and one-time or multiple use connection option.

The removable strip module may also transfer signals from the strip portconnector to the meter through a non-physical connection, such as awireless connection. In such embodiment, the removable strip port modulePCBA would also include a power supply and active components to supporta wireless data transfer module. The meter would also include a wirelesstransceiver to support data transfer. The wireless connection may be astandard type, such as IEEE 802.11, or a proprietary wireless busprotocol. With a wireless removable strip port module, there would be noneed for a cable, and the module would thus “detach” from the meter whenneeded for testing.

Prior to detaching the module from the meter, the meter can beconfigured to charge a power supply on the removable module (e.g., arechargeable battery or capacitor). The module may also be directlycharged through a separate power supply.

As such, in one embodiment, there is provide an analyte measurementsystem including a dedicated hospital meter and one or more removablestrip port modules in wireless communication with the meter. Each of theremovable strip port modules can be kept “bedside” with a patient, andtransmit test data back to the meter when appropriate. As such, eachremovable strip port module can be maintained in a sterile, isolatedfacility, with each patient, while a single dedicated hospital meterreceives and processes that data from each removable strip port module.Further, such system removes the need for the healthcare provider todisinfect the dedicated hospital meter when testing across patients; apractice that many healthcare providers complain about. Further, in suchembodiment, each removable strip port module may transmit data under aunique RFID code. The dedicated hospital meter then includes decodingcircuitry to identify from where the received data is being transmitted.

In certain embodiments, the removable strip port modules describedherein are configured for real-time data/signal transfer to a meter viaa connector. In other embodiments, the removable strip port modulesdescribed herein include a processor and memory unit for signal-to-dataconversion and temporary storage of the analyte data. The removablestrip port module may then be “plugged” into the meter for downloadingof the analyte data.

The following detailed description of the figures refers to theaccompanying drawings that illustrate an exemplary embodiment of ananalyte measurement system. Other embodiments are possible.Modifications may be made to the embodiment illustrated withoutdeparting from the spirit and scope of the present invention. Therefore,the following detailed description is not meant to be limiting.

FIG. 1 illustrates a plan view of an analyte measurement system 100,including an analyte meter 105 and a removable strip port module 110. Asshown, removable strip port module 110 includes a test strip receptacle115 for receiving an analyte test strip 120. While test strip receptacle115 is provided on the opposite side of the output interface of module110, test strip receptacle 115 may be provided on any side of module110. Removable strip port module 110 also includes an output interfacethat is electrically coupled to an input interface (e.g., AFE) ofanalyte meter 110 via a connector 130, such as a cable, cord,serial/parallel bus, or other equivalent connector means. Internalcontacts or traces 140 transmit electrical signals and/or data betweenconnector 130 and a processing unit 150 within a meter housing 160 ofanalyte meter 105.

Further, removable strip port module 110 may be sized and shaped to atleast partially fit within a receptacle formed in housing 160 of analytemeter 105. Module 110 may further include one or more retention tabs162, which are configured to align and/or engage module 110 to receivingtabs 164 on meter housing 160. The interface between module 110 andmeter housing 160 may be configured to be substantially impervious tocontaminants. In another embodiment, module 110 may be coupled to meter105 via a press-fit or snap-fit engagement.

Analyte meter 105 may further include a user interface 170, such as atouch-screen monitor to display test results and receive input from auser.

In one embodiment, connector 130 and internal traces 140 may include avariety of data transfer channels. For example, connector 130 andinternal traces 140 may include three channels plus a ground channel forone type of removable strip port module, three channels plus a groundchannel for a second type of removable strip port module, a channel toidentify the removable strip port module, and a channel to identify whattype of test strip is being used (e.g., glucose, ketone, etc.). As such,connector 130 and internal traces 140 increase the functionality ofanalyte meter 105 by allowing it to be used with multiple differentremovable strip port modules.

FIG. 2 illustrates a plan view of an analyte measurement system 200,including an analyte meter 205 and removable strip port module 210, inaccordance with an alternative embodiment presented herein. As shown,removable strip port module 210 includes a test strip receptacle 215 forreceiving an analyte test strip 220. Removable strip port module 210also includes an output interface that is electrically coupled to aninput interface of analyte meter 205 via a connector 230; such as acable, cord, serial/parallel bus, or other equivalent connector means.Connector 230 may be a fixed length cable, or a retractable cord.Connector 230 may also include a winding mechanism to provide variablelength extension. One such winding mechanism is described in U.S. Pat.No. 6,733,328, which is herein incorporated by reference in itsentirety.

Test strip receptacle 215 is mounted on a PCBA daughter-card 216, forelectrical communication between test strip receptacle 215 and connector230. As shown, test strip receptacle 215 is provided on the oppositeside of the output interface of module 210. However, test stripreceptacle 215 may be provided on any side of module 210.

In the embodiment shown, removable strip port module 110 is notconfigured to fit within a receptacle formed in the meter housing 260.Instead, module 110 is provided as an independent unit that electricallycouples to meter 205 only through connector 230.

Analyte meter 205 may include a user interface, such as a display 270and hard/soft buttons 272.

FIG. 3 illustrates a side view of an alternative connector form betweenremovable strip port module 310 and an input interface 340 in an analytemeter. FIG. 4 illustrates removable strip port module 310 within asection of meter housing 360. In the embodiment shown, removable stripport module 310 is electrically coupled to input interface 340 within ananalyte meter via connector 330. In such embodiment, connector 330 is asoldered wire electrically coupled to leads in module 310. A heat sink317 may be provided for thermal control of connector 330. Electricalcurrent flows from module 310 to interface 340, and then to PCBA 390 viacontacts 380.

FIG. 4 illustrates the removable strip port module 310 installed withinmeter housing 360. A gasket 365 aligns and maintains removable stripport module 310 within meter housing 360. A second gasket 366, such asan o-ring, may also be employed to further align and maintain removablestrip port module 310 in place, as well as keep contaminants fromentering meter housing 360. As shown in FIG. 4, connector 330 may belooped during installation and tucked within meter housing 360.Connector 330 is provided with additional length to provide flexibilityand functionality to the system. In the event that a user wishes toperform an analyte test at a distance from the meter, removable stripport module 310 may be withdrawn from meter housing 360 and an analytetest may be performed while the module 310 and meter remain connectedthrough connector 330.

FIG. 5 is a perspective view of an analyte measurement system 500, inaccordance with one embodiment presented herein. System 500 includes aremovable strip port module 510 and an analyte meter 505. FIG. 5illustrates system 500 prior to insertion of removable strip port module510 into analyte meter 505.

Analyte meter 505 may be similar to analyte meters known in the art. Forexample, analyte meter 505 may include similar structures, functions,and components as the analyte meters described in U.S. Pat. No.7,077,328, which is incorporated herein by reference in its entirety. Asshown, analyte meter 505 includes a display panel 570 for displayinginstructions and/or results from an analyte measurement, and a userinterface 572 for inputting commands to the analyte meter. Analyte meter505 also includes internal processing units (not shown) for the analysisof a blood sample. As such, analyte meter 505 includes means foranalyzing an electrical signal received from removable strip port module510. Analyte meter 505, however, has been modified to lack a fullyintegrated analyte test strip port. Instead, analyte meter 505 includesan input interface (e.g., AFE) with a wireless data transceiver toreceive data from removable strip port module 510.

The transmission of data between removable strip port module 510 and theAFE of meter 505 may be a wireless communication, including, but notlimited to, radio frequency (RF) communication (e.g., Radio-FrequencyIdentification (RFID), Zigbee communication protocols, WiFi, infrared,wireless Universal Serial Bus (USB), Ultra Wide Band (UWB), Bluetooth®communication protocols, and cellular communication, such as codedivision multiple access (CDMA) or Global System for Mobilecommunications (GSM).

As shown in FIG. 5, analyte meter 505 includes a receptacle 505 thatprovides an opening in the analyte meter housing 560. Removable stripport module 510 is designed to fit within receptacle 561. Guide features563 are provided in the meter housing 560 to aide in the insertion andalignment of removable strip port module 510 within receptacle 561.Analyte meter 505 also includes a coupling feature 564 (e.g., a screwhole), which aligns with module 510 for permanent or temporaryattachment. Alternative attachment means may also be employed toremovably (or semi-permanently) attach removable strip port module 510to analyte meter 505.

In one embodiment, for example, the meter housing 560 and internalcomponents are formed of medical grade PC/ABS plastic blend, and mayinclude an anti-microbial plastic such as BAYER BAYBLEND AM120FR. In oneembodiment, meter housing 560 is formed of two or more separatecomponents, which are screwed together using M3 stainless steel screws.Such screws may have heads that differentiate them from the strip portretaining screws. For example, such screws may have Torx heads. Internalscrews may be M2.5 zinc-plated, pan head Philips screws.

FIG. 6 is a perspective view of removable strip port module 510, inaccordance with one embodiment presented herein. FIG. 7 is a rearperspective view of removable strip port module 510. FIG. 8 is anexploded view of removable strip port module 510, in accordance with oneembodiment presented herein.

As shown in FIGS. 6-8, removable strip port module 510 includes a modulehousing 511 with a cap 512. An analyte test strip port 515 is disposedwithin an open end of module housing 511, which is then enclosed (orcovered) by cap 512. In one embodiment, analyte test strip port 515 isan electro-chemical strip port. In an alternative embodiment, analytetest strip port 515 is an optical strip port. As shown in FIG. 8,analyte test strip port 515 is coupled to a PCBA 516, and electricalleads of analyte test strip port 515 are electrically coupled to awireless transceiver 530 on PCBA 516. In one embodiment, module 510 mayfurther include a processor (not shown) and/or power source (not shown)mounted on PCBA 516. The power source may be an individual power source,or a rechargeable power source (e.g., a capacitor) that is charged via aconnection to meter 505 when module 510 is plugged into the meter.

In one embodiment, module housing 511 is formed of a plastic mold, andmore preferably an anti-microbial plastic mold. In alternativeembodiments, module housing 511 may be formed of other suitablematerials such as plastics, rubbers, polymers, or other inert materials.In one embodiment, for example, module housing 511 and internalcomponents are formed of medical grade PC/ABS plastic blend, and mayinclude an anti-microbial plastic such as BAYER BAYBLEND AM120FR. In theembodiment shown in FIG. 8, module housing 511 includes internalalignment features, such as internal alignment baffles 598 and internalalignment grooves 599, to properly align analyte test strip port 515 andPCBA 516 within module housing 511. Such internal alignment features,and structures equivalent thereto, serve as means for aligning ananalyte test strip port within the module housing. A screw hole 597 maybe provided in module housing 511 to attach removable strip port module510 to an analyte meter. A screw for use in screw hole 597 may be astainless steel, pan head Philips, thread-forming screw.

Module housing 511 also includes external alignment features or guides562 and beveled surfaces to further support the proper insertion andalignment of removable strip port module 510 within an analyte meter.Such external alignment features, and structures equivalent thereto,serve as means for aligning a removable strip port module within ananalyte meter.

Cap 512 serves to fully encase analyte test strip port 515 within modulehousing 511. In one embodiment, cap 512 is permanently attached tomodule housing 511 with a hermetic seal 513. In an alternativeembodiment, cap 512 may be removably attached to module housing 511. Inanother alternative embodiment, a gasket means (e.g., a rubber o-ring,fabric, etc.) may be used to seal the gap between cap 512 and modulehousing 511. In the embodiment shown, cap 512 also includes an optionaltab extension 521 to facilitate in the insertion and removal ofremovable strip port module 510 from an analyte meter.

Cap 512 further includes an aperture 514, which provides access toanalyte test strip port 515. In operation, an analyte test strip isinserted through aperture 514 and into analyte test strip port 515. Inone embodiment, aperture 514 provides sufficient clearance to accept awide variety of different analyte test strips form factors. In analternative embodiment, aperture 514 may be customized to receive aspecific analyte test strip form factor. Customizing the aperture sizeor shape to a specific analyte test strip form factor can prevent theuse of non-matching or incompatible analyte test strips with analytetest strip port 515. Aperture 514 may also be formed with a one-wayvalve or port protector to swipe across the surface of an analyte teststrip when the analyte test strip is passed through aperture 514. Suchan embodiment may be used to protect analyte test strip port 515 fromunwanted contaminants. In alternative embodiments, aperture 514 mayincorporate one or more port protectors, such as disclosed in U.S.Patent Application Publication No. 2009/0270696, which is incorporatedby reference herein in its entirety.

In the event that unwanted fluids and contaminants enter throughaperture 514 and comprise the function of analyte test strip port 515,removable strip port module 510 can be removed and replaced with a newremovable strip port module. The replacement of removable strip portmodule 510 can be done without discarding or replacing any of thefunctioning components of analyte meter 505. As such, auser/manufacturer can save money by only replacing the components of thesystem 500 that have actually been comprised. Further, the use of module510 simplifies disinfecting procedures because a healthcare providerneed only clean the module 510, and not the entire meter 505.

FIG. 9 illustrates a plan view of an analyte measurement system 900, inaccordance with one embodiment presented herein. FIG. 10 illustrates aside view of the analyte measurement system of FIG. 9. System 900 issimilar to system 500, except that the wireless capability of theremovable strip port module 510 are removed. In system 900, the linkbetween the output interface of module 510 and the input interface ofmeter 505 is provided by a physical wire or cable connection 930.Connection 930 may be modified and customized to be as long as necessaryfor the applicable use. As such, module 510 may be separated from meter505, and used for bedside testing and/or incubator setting; e.g., in aneonatal application. As used herein, the term “separated” needs torequire a complete disconnection. For example, the module may beseparated from the meter, while still electrically coupled/linked via aconnector. In essence, the module is “separated” from the meter suchthat the module may be drawn to the patient without the need of bringingthe meter to the patient.

FIG. 11 illustrates an ornamental plan view of an analyte measurementsystem having a removable strip port module at least partially insertedwithin a receptacle of the meter housing.

FIG. 12 illustrates an ornamental perspective view of an analytemeasurement system having a removable strip port module at leastpartially inserted within a receptacle of the meter housing.

Certain embodiments presented herein relate to electrical interfaces inmeasurement systems. Measurement systems often have electricalinterfaces that allow them to electrically connect with another systemor apparatus and perform an analysis of an analyte. A system thatmeasures blood glucose levels, for example, includes electricalinterfaces that allow the system to measure the blood glucose level froma small blood sample.

Embodiments presented herein also relate to systems and methods that canimprove the mean time before failure (MTBF) in measurement systems. Byimproving the MTBF, a user is provided with a system that lasts longerand has more accurate performance over time.

Embodiments presented herein also relate to strip connectors or stripports that can be cleaned and/or replaced. The ability to clean orreplace a strip port can prevent the system from experiencing problemsoften associated with port contamination. Blood and other contaminants,for example, can often contaminate a port and make the system unusableor result in inaccurate analysis. A port that can be cleaned or replacedwithout affecting the operation of the system thus increases the MTBF.

Embodiments presented herein provide further advantages such as: theability to upgrade strip port modules as new test strip technologiesevolve; the ability to clean or sterilize a strip port module; and theability to allow users to replace strip port modules without returningthe entire measurement system to the manufacture.

Certain embodiments relate to in vivo (e.g., continuous monitoring)systems. A continuous monitoring system typically includes a sensor thatis worn or placed below the skin, a transmitter that collects glucoseinformation from the sensor, and a receiver that collects theinformation from the transmitter. The sensor can collect glucose levelinformation continuously, periodically, or at other intervals.Advantageously, a user is relieved from having to repeatedly lance hisor her body to collect a blood sample once the sensor is inserted,although the sensor (e.g., an electrochemical sensor that is insertedinto a body) can be replaced. U.S. Pat. No. 6,175,752, which is herebyincorporated by reference in its entirety, discloses additional examplesof a continuous monitoring system.

Embodiments of the invention further extend to kits. Examples of a kitinclude a measurement system with one or more removable strip portmodules. In some kits, different removable strip port modules areprovided for different types of strips. This allows the measurementsystem to be used with different strip form factors. The kits may alsoinclude a plurality of test strips. In certain examples, the measurementsystem may be configured for use with disposable test strips as well aswith test strips that are configured for continuous monitoring systems.Thus, the measurement system may include a receiver to receiveinformation from a transmitter that collects glucose information from aninserted sensor.

Analyte Test Strips

Analyte test strips for use with the present systems can be of any kind,size, or shape known to those skilled in the art; for example,FREESTYLE® and FREESTYLE LITE™ test strips, as well as PRECISION™ teststrips sold by ABBOTT DIABETES CARE Inc. In addition to the embodimentsspecifically disclosed herein, the systems of the present disclosure canbe configured to work with a wide variety of analyte test strips, e.g.,those disclosed in U.S. patent application Ser. No. 11/461,725, filedAug. 1, 2006; U.S. Patent Application Publication No. 2007/0095661; U.S.Patent Application Publication No. 2006/0091006; U.S. Patent ApplicationPublication No. 2006/0025662; U.S. Patent Application Publication No.2008/0267823; U.S. Patent Application Publication No. 2007/0108048; U.S.Patent Application Publication No. 2008/0102441; U.S. Patent ApplicationPublication No. 2008/0066305; U.S. Patent Application Publication No.2007/0199818; U.S. Patent Application Publication No. 2008/0148873; U.S.Patent Application Publication No. 2007/0068807; U.S. patent applicationSer.

Integrated with Lancing Device

In another embodiment, an analyte measurement system may include anintegrated analyte test meter and lancing device for providing a bodilyfluid sample, such as a blood sample, and measuring an analyteconcentration, such as a blood glucose concentration. Examples of suchintegrated systems include systems and devices described in US PublishedApplication Nos. US2007/0149897 and US2008/0167578, the disclosures ofeach of which are incorporated herein by reference in their entirety.

Calculation of Medication Dosage

In one embodiment, the analyte measurement system may be configured tomeasure the blood glucose concentration of a patient and includeinstructions for a long-acting insulin dosage calculation function.Periodic injection or administration of long-acting insulin may be usedto maintain a baseline blood glucose concentration in a patient withType-1 or Type-2 diabetes. In one aspect, the long-acting medicationdosage calculation function may include an algorithm or routine based onthe current blood glucose concentration of a diabetic patient, tocompare the current measured blood glucose concentration value to apredetermined threshold or an individually tailored threshold asdetermined by a doctor or other treating professional to determine theappropriate dosage level for maintaining the baseline glucose level. Inone embodiment, the long-acting insulin dosage calculation function maybe based upon LANTUS® insulin, available from Sanofi-Aventis, also knownas insulin glargine. LANTUS® is a long-acting insulin that has up to a24 hour duration of action.
